The control strategy encompasses regulating both active and reactive power, accomplished by manipulating the load angle and the magnitude of the inverter’s output voltage. By adjusting the reactive power injected into the grid, the controller ensures that maximum active power is fed into the grid at a unity power factor.
The control system incorporates a maximum power point tracker (MPPT) that continuously determines the optimal power for the operational PV array. The control strategy encompasses regulating both active and reactive power, accomplished by manipulating the load angle and the magnitude of the inverter’s output voltage.
This paper proposes a robust voltage control strategy for grid-forming (GFM) inverters in distribution networks to achieve power support and voltage optimization. Specifically, the GFM control approach primarily consists of a power synchronization loop, a voltage feedforward loop, and a current control loop.
The multilevel inverter is also regulated to inject this maximum power into the grid, regardless of atmospheric conditions, and to control both active and reactive power, thus ensuring a unity power factor on the network side. This approach aligns with the methodologies discussed in , .
